I've subscribed to Tabulizer for several years now, and seen steady and remarkable improvements all the time. The Ruleset Wizard for customized tables is really great, and support is stellar! Responsive tables support is an incredible addition. I can highly recommend this product
I'm a fan of the Artetics components in general, and this is no exception. Breeze to install, many good "out of the box" clock styles, easy to calculate timezones and my client is very pleased. Well done, thanks Artetics!
Hazzaa has made one fine addition to my core stable of Joomla components. Its really the best solution for custom registration forms and his support after the sale has been the best I have experienced. The one suggestion would be to keep improving the Tutorials area to address common issues.
